/deep-implement, a Claude Code plugin

/deep-implement is the final step in the deep planning pipeline. It takes the section files generated by /deep-plan and implements them one by one with TDD methodology, integrated code review, and a structured git workflow.

Where /deep-plan produces the what and why, /deep-implement handles the how—methodically, with tests first and human-in-the-loop code review at each step.

For large projects, use /deep-project first to decompose vague requirements into focused specs, then /deep-plan each spec, then /deep-implement the resulting sections.

I built /deep-implement because after I'd automated my planning workflow through /deep-plan, I found myself executing the same steps over and over to actually implement the produced section files. Why not have Claude orchestrate it for me?

/deep-implement keeps the human in the loop through code review and managing context. In the future /deep-implement will look to provide even more automation.

TL;DR

/plugin marketplace add piercelamb/deep-implement
/plugin install deep-implement
/plugin enable deep-implement
/deep-implement @planning/sections/.

Overview

deep-implement orchestrates a disciplined implementation workflow:

Read Section → TDD Implementation → Code Review → Interview → Commit → Next

For each section from /deep-plan, the plugin:

• Implements with TDD: Write tests first, then implementation
• Runs Code Review: A dedicated subagent reviews staged changes
• Interviews You: Triage findings, get your input on real decisions
• Updates Section Docs: Records what was actually built back into the section file
• Commits Atomically: One commit per section with review trail
• Tracks Progress: Resume from any point after interruption

By the end, you have production-ready code with a git history that tells a clear story—and section documents that serve as living documentation of what was actually built, not just what was planned.

The Deep Trilogy

This plugin is part of a three-plugin pipeline for turning ideas into production code:

/deep-project (decompose) → /deep-plan (plan) → /deep-implement (build)
